title: [Psoriatic arthritis: case report of acute HLA-B27 positive polyarthritis preceding the onset of typical skin changes].
abstract: Psoriasis usually occurs many years before development of arthritis. This is a case report of a patient with acute polyarthritis affecting both peripheral joints and the left sacroiliac joint, preceding the appearance of typical skin manifestations for almost two months. A 44-year-old male mechanic was admitted to our institution for acute additive polyarthritis. Inflammatory synovitis primarily affected large peripheral joints (knees, ankles) in an asymmetrical pattern, with a concomitant development of unilateral sacroiliitis and later with asymmetrical involvement of several proximal and distal interphalangeal joints of the hands and feet. There were also signs of enthesopathy of the right heel. Arthritis was not proceeded by infection of the lower genital or gastrointestinal tract or serological and bacteriological evidences of streptococcal or HIV infection. Laboratory findings showed an erythrocyte sedimentation rate (92 in the first hour), positive histocompatibility antigen HLA-B27 and an increased level of acute phase reactants. Almost two months after affecting the locomotor system a typical psoriatic rash developed, first affecting the scalp and then spreading over the trunk and extremities. It was accompanied by severe onychodystrophy. The patient underwent intensive treatment with methylprednisolone (1.5 mg/kg) and cyclosporine A with significant results.
